Why (for the first time) is CO2 going up simultaneously with a rise in temperature?

Question

In previous natural warmings, the rise in CO2 lagged hundreds of years behind the rise in temperature.

That was because the warming started for other reasons and CO2 was released from ocean waters as they warm. The process HAS to take hundreds of years, as cold deep ocean water slowly circulates up to the surface.

Most all scientists think this proves THIS warming was not caused naturally, but mostly by CO2. Anyone got an alternative explanation?

Answer 1

The planet is quite capable (as i am sure you know) of releasing 3 times , 10 times ,  or more of Co2  into the atmosphere as we see today. Do not be so quick to misinterpret the data . If you look at the ice core reconstructions , you do see the lag of Co2 behind temperature rise. You also see though , points in which temperature begins to fall ,  yet Co2 keeps rising. This is also a part of the "lag" effect  , due to the vastness of the oceans. The rise in Co2 that we see today is in response to a world that began warming 150 years ago. That combined with the fact that we have had a cooling period over the past 5- 10 years looks very similar to points in the ice core reconstructions where temp began to fall and Co2 kept rising. The bottom line is this.... Whatever the amount of Co2 in the air , we know how much we add and that amount is nowhere close to explaining any increase we observe. Termites release more Co2 in one year than we do. So....Alternative explanation???   Solar Forcing .

The bottom line:

2.4E15 kg CO2 in the atmosphere

1.4E17 kg CO2 in the oceans

5E14 kg CO2 biomass flux

2E13 kg CO2 added yearly from fossil fuels

So the rise from 330 to 380 ppm (+15% in 29 years) would be caused by man adding a fraction of a per cent to the total of the CO2-stream?

If man would burn fossil fuels at the rate of 1978 for 7000 years, the amount of CO2 in the CO2-stream would double. I can live with those numbers.

Dana1981.... your runaway feedback theory needs some work. You cant have it both ways. you are trying to say that Co2 does lead temperature , it just needs some sort of kick start. That is inaccurate . Co2  does not work that way. Nowhere in the temperature reconstruction do we see the cause and effect you are making the argument for. Co2 is acting just as it should as a gas that expands when it is warmed. Co2 is a minor GHG that reacts , not causes, only to the energy that is put into the system and that energy comes from one place....The Sun. You simply cannot back your theory up. Try this instead

Answer 2

Frequently in the past changes in solar output or normal long term variances in the earth's orbit can warm the earth slightly, releasing CO2 from the ocean, causing additional warming.

Sometimes volcanoes have erupted long enough to emit enough CO2 to trigger warming (as with the Siberian Traps volcanoes, which caused the Permian Triassic Extinction).

This time however we know it's not the sun or the earth;s orbit, and no major volcanoes have been erupting for thousands of years.  We've also been measuring CO2 levels so we've seen the increase, and we have confirmed through carbon isotope analysis that the additional CO2 is from fossil fuels.

It all fits.  There's no credible alternate hypothesis, or many peer-reviewed scientific papers would have been written on the subject, and you'd have scores of links to those papers in the skeptical responses (instead of a collection of poorly supported claims).

Answer 3

The answer is simple and an expected result - increasing CO2 is causing global warming.  It always has in the past as well, except in the past, another forcing caused the initial warming before CO2 feebacks began to dominate, as I discuss in the link below.

Oftentimes the simplest answer is the correct one.

Answer 4

Skeptics are fascinating. They' re willing to lie repeatedly to uphold their double standards. They typically admire faith more than science and will say things like "just because you can't see it doesn't mean it's not real" in one corner of their mouth and in the other corner of their mouth they will say "how do you know Bob, you weren't there during the last climate cycle or during the time of the dinosaurs" etc....

They believe what they want to regardless of evidence, and this is why they are so dangerous.

Answer 5

You admit freely that warming causes increases in CO2. If this is the case, where in recent history is the run away warming that is projected by alarmists? What kept the medieval warm period and others before it from becoming catastrophic?

Answer 6

Bob, who was there during the last cycle to take these measurements?

Please enlighten us if you can.

Or are we just supposed to accept anything you and your buddies say?

Answer 7

Well first there is very little CO2 in the oceans/. Do this experiment to show what happens when CO2 water . Take a Coke and dump in a small amount of salt and watch the CO2 come out. The plants are doing a great job of recycling Co2 .
